I'm a huge Fred Williamson fan and a moderate-to-strong Lucio Fulci fan, so I have no idea why I haven't yet seen Rome 2033 - The Fighter Centurions(1984). But after watching the film's opening sequence (included after the break) and learning that Rome 2033 (aka Warriors of the Year 2072, for some reason) is based on a life-and-death gameshow called Killbike, and features a killer score, it's been bumped to the top of my list.
